When a 4m great white shark circled a group of spear fishermen on the Gold Coast, you could forgive them for using some colourful language. After all the word 'shark' is basically an amalgamation of two of Australia's favourite swear words.

(Take a minute to figure that one out in your head. Go on -- you'll be glad you did.)

Instead, the seasoned divers called it 'beautiful and graceful' describing the whole encounter as 'memorable'.

It looks memorable alright. As in 'I must remember to burn my soiled wetsuit', memorable.
